+# Config LLamaSharp
+
+BotSharp contains LLamaSharp plugin that allows you to run local llm models. To use the LLamaSharp, you need to config the BotSharp project with few steps.
+
+## Install LLamaSharp Backend
+
+Before use LLamaSharp plugin, you need to install one of the LLamaSharp backend services that suits your environment.
+
+- [`LLamaSharp.Backend.Cpu`](https://www.nuget.org/packages/LLamaSharp.Backend.Cpu): Pure CPU for Windows & Linux. Metal for Mac.
+- [`LLamaSharp.Backend.Cuda11`](https://www.nuget.org/packages/LLamaSharp.Backend.Cuda11): CUDA 11 for Windows and Linux
+- [`LLamaSharp.Backend.Cuda12`](https://www.nuget.org/packages/LLamaSharp.Backend.Cuda12): CUDA 12 for Windows and Linux
+
+**Please install the same version of LLamaSharp Backend with the LLamaSharp in BotSharp.Plugin.LLamaSharp.csproj.**
+
+![Check LLamaSharp Version](assets/check-llamasharp-version.png)
+
+```shell
+# move to the LLamaSharp Plugin Project
+$ cd src/Plugins/BotSharp.Plugin.LLamaSharp
+# Install the LLamaSharp Backend
+$ dotnet add package LLamaSharp.Backend.Cpu --version 0.9.1
+```
+
+## Download and Config Local LLM Models
+
+LLamaSharp supports many LLM Models like LLaMA and Alpaca. Download the `gguf` format models and save them in your machine.
+
+We will use a [Llama 2](https://huggingface.co/TheBloke/llama-2-7B-Guanaco-QLoRA-GGUF) model in this tutorial.
+
+After downloading the model, open the `src/WebStarter/appsettings.json` file to config the LLamaSharp models. Set the `LlmProviders` and `LlamaSharp` fields to correct settings as your computer. For example:
+
+```json
+{
+    ...,
+    "LlmProviders": [
+        ...,
+        {
+            "Provider": "llama-sharp",
+            "Models": [
+                {
+                "Name": "llama-2-7b.Q2_K.gguf",
+                "Type": "chat"
+                }
+            ]
+        },
+        ...
+    ],
+    ...,
+    "LlamaSharp": {
+        "Interactive": true,
+        "ModelDir": "/Users/wenwei/Desktop/LLM",
+        "DefaultModel": "llama-2-7b.Q2_K.gguf",
+        "MaxContextLength": 1024,
+        "NumberOfGpuLayer": 20
+    },
+    ...
+}
+```
